Read the feedback there:
"So, as you are submitting the first node(s) under network_bus: bus at 5, you
should have this added into your patchset, instead of sending out with
none."
Plus simple bus within MMIO node needs unit address. IOW, don't mix MMIO
with non-MMIO. I also suspect this does not pass checks, so the tools
can do our review...
Best regards,
Krzysztof
